Nursing Elites

1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. A client is receiving furosemide. Which of the following laboratory values should the nurse monitor?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion through increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. Monitoring sodium, calcium, and magnesium levels is not typically associated with furosemide therapy, making choices A, C, and D incorrect.

3. The nurse is making a home visit with a client diagnosed with Alzheimer's disease. The client recently started on lorazepam (Ativan) due to increased anxiety. The nurse is cautioning the family about the use of lorazepam (Ativan). The nurse should instruct the family to report which of the following significant side effects to the healthcare provider?

• A. Paradoxical excitement
• B. Headache
• C. Slowing of reflexes
• D. Fatigue

Correct answer: A

Rationale: The correct answer is A, paradoxical excitement. Lorazepam can cause an unexpected response of paradoxical excitement, which should be reported to the healthcare provider. This reaction is characterized by increased anxiety, restlessness, and agitation instead of the expected calming effect. Choices B, C, and D are incorrect because headache, slowing of reflexes, and fatigue are more common side effects of lorazepam and may not warrant immediate reporting unless severe or persistent.

4. A client is learning about preventing hip dislocation before total hip arthroplasty. Which instruction should be included?

• A. Avoid bending the hip more than 90 degrees
• B. Avoid lying on the unaffected side
• C. Avoid crossing the legs at the knees
• D. Avoid keeping the legs in a neutral position

Correct answer: C

Rationale: The correct instruction to prevent hip dislocation after total hip arthroplasty is to avoid crossing the legs at the knees. This position can put stress on the hip joint and increase the risk of dislocation. Choices A, B, and D are incorrect. Bending the hip more than 90 degrees, lying on the unaffected side, or keeping the legs in a neutral position are not directly related to preventing hip dislocation in this context.

5. A client has an NG tube that needs to be irrigated every 8 hours. Which solution should the nurse use to maintain fluid and electrolyte balance?

• A. Tap water
• B. Sterile water
• C. 0.9% sodium chloride
• D. 0.45% sodium chloride

Correct answer: C

Rationale: The correct solution to maintain fluid and electrolyte balance during NG tube irrigation is 0.9% sodium chloride. This solution is isotonic and helps prevent electrolyte imbalances. Using tap water or sterile water can lead to electrolyte disturbances due to their hypotonic nature, while 0.45% sodium chloride is hypotonic and may cause further imbalances in the client's electrolyte levels.
